The base asce functions create/free page tables open-coded to make sure that the returned asce and page tables do not make use of any enhanced DAT features like e.g. large pages. This is required for some I/O functions that use an asce, like e.g. some service call requests. Handling of virtual vs physical addresses is missing; therefore add that now. Note: this currently doesn't fix a real bug, since virtual addresses are indentical to physical ones.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
